The cardiac output module from Quantium Medical, the qCO, features noninvasive measurement of cardiac output, stroke volume and cardiac index. The qCO features Adaptive Neuro Fuzzy Inference System for higher precision.
Heart rate variability (HRV) is the physiological phenomenon of variation in time between heartbeats. This measure is related to respiration, blood pressure and other vital signs, thanks to the relation between the central nervous system and the pacemaker cells.
The qCO-HRV module offers a complete analysis of the HRV, featuring parameters with a strong association to the degree of  sepsis (inflammation).
PARAMETERS DEFINITION
ECG curve Graphic representation of the electrical activity of the heart.
HR Refers to the speed of the heartbeat, specifically the number of heartbeats per unit of time.
Energy in HF band Energy in the 0.15-0.4 Hz frequency bandwidth. This frequency band is related with SNP activity, therefore HF components increase when the heart rate decreases.
RMSSD Reports the short-term variations of RR intervals and is used to observe the influence of the parasympathetic nervous system (PNS) on the cardiovascular system.
SDSD Standard deviation of  successive differences of the RR intervals.
pNN50 Percentage of the RR intervals that differ more than 50 ms. A high value of pNN50 gives us information about the spontaneous variation of the heart rate.
Impedance Curve Graphic representation of the impedance.
Cardiac Output (CO) Amount of blood the heart pumps through the circulatory system in one minute.
Stroke Volume (SV) Amount of blood put out by the left ventricle of the heart in one contraction.
Cardiac Index (CI) Relatesthe cardiac output (CO) to body surface area (BSA), thus relating heart performance to the size of the individual.
